Which of the tables represents a function?

Answer:

C and E

Step-by-step explanation:

I just took the test and got a 100%  :)

This question is based on the system of equation. Therefore, the correct options are (C) i.e. y=-1/6x+3 and (E) i.e.  y = 1/2x-1, are the equations of solution to the system is (6,2).

Given:

The solution to the system is (6,2).

We need to select all the equations that could be the other equation in the system.

For solving this question, we will be putting the given co-ordinates in the  given options and check.

A. y = - 3x

Putting the co-ordinates (6,2).

We get,

2 [tex]\bold{\neq}[/tex] -18

B. y=-3/2x+6

Putting the co-ordinates (6,2).

We get,

2 [tex]\bold{\neq}[/tex] -3

C. y=-1/6x+3

Putting the co-ordinates (6,2).

We get,

2 = 2

D. y=2/3x-1

Putting the co-ordinates (6,2).

We get,

2 [tex]\bold{\neq}[/tex]3

E. y=1/2x-1

Putting the co-ordinates (6,2).

We get,

2= 2

F. y=4x-2

Putting the co-ordinates (6,2).

We get,

2[tex]\bold{\neq }[/tex] 22

Therefore, the correct options are (C) i.e. y=-1/6x+3 and (E) i.e.  y=1/2x-1, are the equations of solution to the system is (6,2).

Step-by-step explanation:

Answer:

13613.46 cm^3

Step-by-step explanation:

Height of the conical top= 25 cm

Diameter of the conical top = 20 cm

Radius of the conical top = 10 cm

[tex]We\ know\ that,\\Volume\ of\ a\ cone\ = \frac{1}{3}\pi r^2h\\Hence,\\Volume\ of\ the\ conical\ top\ = \frac{1}{3}\pi 10^2*25 = \frac{1}{3} \pi 100*25\\= 833.3\pi\ cm^3[/tex]

Height of the cylindrical base = 35 cm

Diameter of the cylindrical base = 20 cm

Radius of the cylindrical base = 10 cm

[tex]We\ know\ that\ ,\\Volume\ of\ a\ cylinder\ = \pi r^2h\\Hence,\\Volume\ of\ the\ cylindrical\ base = \pi* 10*10*35\\=3500\pi\ cm^3[/tex]

[tex]Hence,\\Volume\ of\ the\ given\ figure\ = Volume\ of\ the\ conical\ top\ + Volume\ of\ the\ cylindrical\ base\ \\Hence,\\Volume\ of\ the\ given\ figure\ =833.3\pi +3500\pi \\=(3500+833.3)\pi \\=4333.3\pi \\=13613.46 cm^3[/tex]

Answer:

13,614cm³

Explanation:

There are 2 solid shapes in the object;

A cylinder and A cone

Volume of the cylinder = πr²h

Volume of the cone is 1/3πr³h

h of cone = 25cm

h of cylinder = 35cm

d of the cylinder and cone = 20cm

r = d/2 = 10cm

Volume of the cylinder = πr²h

= π(10)²×35 = 10,996cm³

Volume of the cone = 1/3πr²h

= 1/3π(10)²×25 = 2618cm³

Therefore the total volume of the object above =

Volume of the cylinder + Volume of the cone =

10,996cm³ + 2618cm³ = 13,614cm³

Answer:

12.5 inches

Step-by-step explanation:

Given the equation for the cross section of a parabolic satellite TV dish:

y=1/50x^2

Equation of a parabola :

(y - k) = 1/4p * (x - h)^2

Distance of the focus from the Vertex = p

Comparing both equations :

1/4p * (x - h)^2 = 1/50 * x^2

4p = 50

Divide both sides by 4

4p/4 = 50/4

p = 12.5 inches

Answer

y= 3/2 x  - 2

Step-by-step explanation:

so you have to find the slope which would be

m =  

y2 - y1

x2 - x1

then you find you points that you are using (2, 1) and (0, -2)

when you plug it in it is

m=

-2-1

0-2

you simplify the numbers and get rid of the negatives to get m=3/2 x

then your y intercept is where your line meets the y axis or wherever x=0

so your y intercept is (0, -2) so the b = -2

Answer:

8.75 +/- 0.657

Step-by-step explanation:

The 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617

A confidence interval is a range around a measurement that conveys how precise the measurement is.

Given that, The sample data were roughly symmetric with a mean of 8.75 hours and a standard deviation of 1.5 hours, the confidence level value is 90%

confidence interval = x ± z·s/√n

= 8.75±1.645·1.5/√16

= 8.75±0.617

Hence, the 90% confidence interval for the mean amount of sleep this population of students gets on a typical weekend night is 8.75±0.617
